[PATCH] PNPACPI: support shareable interrupts
ACPI supplies a "shareable" indication, but PNPACPI ignores it. If a PNP
device uses a shared interrupt, request_irq() fails because the PNP driver
can't tell whether to supply SA_SHIRQ.
This patch allows PNP drivers to test
(pnp_irq_flags(dev, 0) & IORESOURCE_IRQ_SHAREABLE)
